Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71744, here are decompositions:
- 3 + 71741 = 71744
- 31 + 71713 = 71744
- 37 + 71707 = 71744
- 73 + 71671 = 71744
- 97 + 71647 = 71744
- 151 + 71593 = 71744
- 181 + 71563 = 71744
- 193 + 71551 = 71744
Showing the first eight; more decompositions exist.
